SPECIFICATION forming part of Letters Patent No. 559,755, dated May 5,1896.

Application filed February 18,1890. Serial No. 340,920. (No model.)

To @ZZ whom, it may concern:

Be it known that I, CHRISTOPHER LATHAM SHOLEs,a citizen of the UnitedStates,residin g at Milwaukee, in the county of Milwaukee and State oflWisconsin, have invented certain new and useful Improvements in Type-\Vriting Machines, of which the following is a speciiication.

This invention relates to type-writing maro chinos; and it consists invarious features, details, and combinations hereinafter set `forth,having for their object the simplification and improvement of themachine, and particularly increase in eihciency.

Figure l is a perspective View ofthe machine complete; Fig. 2, atop planview 5 Fig. 3, a vertical section in the direction of travel of thepaper-carriage; Fig. Lt, a side or end eleva tion; Fig. 5, a perspectiveview showing the 2o platen-roll shifted from its normal position to aposition in which the line being` printed may be viewed by the operator;Fig. (5, a bottoni plan view; Figs. '7 to ll, detail views hereinafterreferred to.

The frame of the machine may be of any suitable construction, but ishere represented as consisting' of a top plate or table A, sustained byfour legs or uprights B, a bar C, extending across the front and ends ofthe 3c machine, as shown in Figs. l and G, and a platform D below thetop or table A. The top or table A is formed witha large opening ofcircular form, and below the top or level of the table there is formedan inwardly-projecting ledge a concentric with the opening in the top.

Nithin the opening, resting upon. and supported by the ledge a, is abasket E, which may be conveniently cast in one piece, and

4o which bears the clips or brackets F of the type-bars G with thetype-bars pivoted in them, as best shown in Figs. l, 2, and 3.

lWithin the basket and at or near its lower end is placed. a pad orcushion H, against which the type-bars G strike and rest when they fallafter a stroke, the purpose being to deaden the sound and, at the sametime, cause all the type-bars to assume the same position when down. Bythus causing each type-bar to fall to the same level, each is requiredto travel the same distance in rising to the platen, and consequently ifeach keylever be given the same leverage all the keys will require alike stroke, a feature very dcsirable to secure in this class ofmachines. 5 5 The basket E may be held in place by screws or otherwiseand may be readily removed from the frame with all the type-bars in it,if desired, thus giving great facility of repair and adjustment. 6o

The clips F are stamped from thin metal, preferably sheet-steel, and areof the form shown in Fig. 7--thatis to say, cach consists of ahorizontalbodT or plate havi ng upturned sides, the forward or inward ends ofwhich rise to form ears l), which are provided with perforations c toreceive the pivots or the journals of the type-bar G.

The body or plate of the clip is formed with an elongated opening (Z topermit the passage 7o of a fastening-screw e through it, by which tosecure it to the top ring of the basket, the size of opening clpermitting adjustment of the clip longitudinally and laterally.

I, Fig. 8, indicates a washer-plate which is 7 5 curved to conform tothe curvature of the upper ring of basket E and is slotted to receivethe upright sides of the clips F. The portions between the slots areperforated to permit the passage of the fastening-screws c, 8o whichsecu re a firm bearing upon the washerplate, and thus afirm clamping ofthe clips is insured.

The platform D is furnished on its upper side with a series of posts J,in each of which is mounted a lever K, one end of which connects with atype-bar G and the other end of which connects with the key-leverbelonging to such type-bar. The manner of and means for thus connectingthe type-bars and key 9o levers and transmitting motion from one to theother through the intermediate levers li is illustrated in Figs. l, 3,and et. As shown in said figures, each type-bar is formed withlaterally-proj ecting studs c' in rear of its piv- 95 ots, which studsenter sockets or eyes in the two members of a bifurcated spring-yokeforming the upper end of a stem or rod f, whichstem constitutes theupper section of a three-part connecting-rod L. rlhe lower roe section gof rod L has its lower end jointed in any convenient manner to the leverK below it, and its upper end is joined to the lower end of the uppersection f by means of a turnbuckle 0r swivel 7L, eithertapped to receivethe reversely-threaded ends of parts f and g or swiveled upon one partand tapped to receive the other. These constructions are substantialequivalents and are both common in mechanical structures wherever, as inthe present instance, it is desirable to provide for varying the lengthof the rod or link .connecting two parts. From the end of lever K,opposite that to which the link or connecting-rod L is attached, anotherlink or connecting-rod M passes to and connects with a key lever or barN, of which latter there is one for each type-bar, each pivotallysupported in a slotted post or hanger fr', extending downward from theunder side of platform D, as shown in Fig. 3. Each key-lever N may, ifdesired, be furnished with a linger-button, and so connected with thespacing mechanism of the machine as to cause the advance of the platenone space for each depression; but I prefer to adopt a somewhatdifferent plan of construction and operation, which is illustrated inFigs. l, 2, and i. Upon referring to these figures it will be seen thata board or fiat bar O extends across the front of the `machine from sideto side, and is perforated to permit the passage through it of a seriesof stems P, the lower ends of which are connected with the front ends ofthe key-levers N, one to each lever. The upper ends of the stems P areheaded to prevent the board or bar O from being lifted above them, andopposite the head of each stem there is placed upon the board or bar O acharacter to indicate what printing-character answers to or iscontrolled by such stem. The board O is carried upon the forward ends oftwo arms or bars Q, which, at their rear ends, are made fast upon arock-shaft R, carried upon pointed screws or other pivots in the mainframe of the machine.

Rising from the rock-shaft R, at or about its mid-length, is an uprightarm S, which carries a head j of the form shown in Figs. 2 and 9.

A spring T (shown in Fig. et and secured to the rear side of the mainframe of the machine) bears upon the upright arm S, and throws the samebackward, and holds it normally against a stop 7c. (Shown in Fig. 2.)This stop is represented in the drawings in the form of a spring-armprojecting laterally from an upright U, which rises from the rear of themain frame and bends forward horizontally over the spacing-rack of theplatencarriage, as shown in Figs. 2 and 4. The spring T, bearing againstthe arm S, causes the rock-shaft to be turned and thewrrms Q and board Oat the front of the machine to be raised and normally held in anelevated position, so that the board is brought'up directly beneath theheads of the pins or stems board O and thereby actuating the spacing dogor head j, nor can the board itself be depressed independently of thestems without thus actuating the feed dog or head. It will therefore beseen that whenever a stem is dcpressed for the purpose of printing acharacter, or whenever the board is depressed independently of thestems, the carriage, which is permitted to advance one tooth each timethe feed-dog is thrown forward, will advance one space. The board,extending fr om side to side of the frame of the machine, and therebeing a considerable blank space at each end of the board, and also fromend to end thereofl between the rows of stems T, the operator mayreadily depress the board without mov-- ing his hand from the positionwhich it occupies in striking the keys or stems.

NVhile in the drawings I have represented the indicators by which toselect the particular character or characters desired as applied to theboard O, opposite the particular stem correspondin g with suchindicator, it is manifest that the indicator letters or characters maybe applied directly to the heads of the stems.

V and lV represent, respectively, flat and eylindrical rods or barsextending parallel with the board O at the top of the main frame of themachine, which rods or bars serve as supports and guides for thetraveling platencarriage X. (Shown in Figs. l, 2, Ll, and 5.) Asrepresented in said figures, this carriage consists of a rectangularframe of metal supported at its forward side upon a roller or rollers Zand at its rear side by perforated ears or lugs m, which encircle andslide upon the guide-rod WV.

Secured to and carried by the ears or lugs m is a bar Y, parallel withthe guide-rod XV, and provided with a series of vertical slots extendingtransversely through the bar from front to rear. In each of said slotsis loosely mounted a slide or tumbler Z, having at each end an ear orlip n, by which its longitudinal movement through the bar Y in eachdirection is limited. The sliding dogs or tumblers Z are free to moveback and forth through the bar Y, and are moved forward through the sameby the feed dog or head j one at a time, and are restored to theirnormal position or moved rearward by a guard or plate A', which inclinesfrom a centralpoint toward the front of the machine at each end and iscarried by the overhan gin g end of the upright or standard U. y

lVhen the line has been completed, or it is desired to recede thecarriage preparatory to starting a new line, or for any other purpose,the forward ends of the dogs or tumblers come into contact with theincline face of the IOO IIO

guard A', are by it moved backward through the bar Y, and are then inposition to be alternately engaged and moved forward by the head j. Thisaction will be readily understood by referring to Figs. 2 and 9, inwhich it will be seen that the head j is formed with two upright faces oand p, connected by a third upright face q, formed by cutting away theforward corner of heady.; as shown in said figures, to an extent equalor somewhat more than equal to the thickness of one of the slides ortumblers Z. The face p forms a stop, by which the foremost slide ortumbler Z is arrested, whereby the carriage is held against advance.lVhen, however, the head j is thrown forward by the depression of boardO, the face q bearing directly against the rear end of such slide ortumbler carries it forward through the bar Y until its rear end isforward of the normal position ot' head L7'. As the head j recedes orreturns to its normal position, the face p passes out of contact withthe slide or tumbler just advanced, the face o preventing the advance ofthe carriage during this backward movement of the head, by reason of itsbeing directly in the path of the next slide Z and bearing against theside face of such slide until face q reaches the rear end of the slideor tumbler, whereupon the carriage moves forwardagain until the sliderests against face p. These several operations are repeated at eachdepression of board 0 and a step-by-step advance of the carriage is thussecured.

For the purpose of moving back the slides or tuinblers Z, preparatory totheir actuation by the head j, the doubly-inclined guard A' isfurnished. 'lhis guard being held in a fixed position, the forward endsof any of the slides or tuinblcrs Z, that may be forward or in advanceof their normal positions, will ride upon one or the other incline ofthe guard, according to the direction in which the carriage is moved,and will be thereby forced back to their first or usual position. Thefront face of head j is beveled, as shown, so that when the carriage isreceded the slides or tumblers may not lock against the same, but may bemoved forward suiiiciently to pass the head, being at once moved backagain by the guard A. The carriage is advanced by a spring B', securedto the bar C of the main frame, and preferably coiled or vbent 'into theforni indicated in Fig. 6, which is a bottom view of the machine, or ofso much thereof as belongs to the carriage-advaucin g mechanism.

G' indicates a bar or sweep, one end of which is pivotallyattached tothe bar C of the frame and the other end of which extends upward at therear side of the machine and is connected by a link D with the bar Y orother part of the carriage. This bar C is formed with two .lateralbranches fr and s near its pivot ond, the former provided with a seriesof notches at different distances from the pivot of the bar C', in oneor another of which notches will be seated one end of a link t, by whichthe arm fr and the free end of spring B' are connected. By moving thelink toward or from the end of arm r the leverage may be varied and thespring caused to act with greater or less force, as required. From theend of arm s a bar or link u extends to and is pivotally connected witha flat bar E', the two ends of which project through slots or openingsin the side portions of bar C of the main frame, as shown in Figs. l, 2,4:, and 6.

As will be readily understood upon reference to Fig. G, the spring Btends to swing the bar or sweep C about its pivot or cent-er of motion,and as this action takes place the outer end of arm s will swing towardthe front of the machine, and as the bar is returned to itsstarting-point by the recession of the carriage the arm s will movebackward or away from the front of the machine. In thus moving back andforth the arm S will, through link u, impart a forward and backwardmovement to the bar E', the two ends of which are caused by a guide-rodF', Fig. G, to move alike.

Rising from each end of the bar E is an upright or standard G', (wellshown in Figs. l, 3, and 4,) each of which carries a horizontal stem orspindle Il below the table A to receive a ribbon-spool l and each ofwhich has above said table a lateral arm J which serves as a ribbonsupport and guide to raise the inking-ribbon above the type-bars and tohold it in proper relation to the platen-roll. A nut fv, screwed uponthe end of each stem or spindle ll, prevents the spool from working off.

The ribbon spools and guides being carried by and moving with the bar E,it follows that as the bar is moved back and forth the ribbon will bemoved transversely to its length across the printing-point, and that asa consequence the entire width of the ribbon will be utilized instead ofmerely a narrow line thereof, as is usually the case.

To cause the longitudinal travel of the ribbon the spools l are bothmade with a ratchet wheeler disk w at one end with which engages a dogor pawl carried by a swinging arm or lever y, pivoted, one to eachupright or standard G, as shown in Fig. 3. A spring e' serves tonormally draw and hold back each of the arms or levers yy orto returneach after aforward movement. A throw-out lever K' is pivoted to eachstandard or upright G" and engages beneath a projection on the dog orpawl zo, serving to lift and hold the saine out of engagement with itsratchet wheel or disk when desired, only one pawl and disk being in.engagement at any one time. The upper ends of the levers 1j bear againstoblique guides or ways a', whereby as the bar E moves toward the rear ofthe machine the levers {1/ are thrown inward, the springs by returningthem, to their first positions as the bar again moves forward. Eachratchet-wheel vw is prevented by a click-spring or detent b' IOO IIO

from being turned backward by the pawl or dog on its backward movement.This detent must be thrown out of engagement with its ratchet-wheelwhenever the pawl is, so as to permit backward rotation and allow theribbon to be drawn off and wound upon the spool being actuated, or elsethe ribbon-spools must be transposed when the direction of travel is tobe reversed. It is preferred to disengage the detent from theratchet-wheel, as handling` of the ribbon is thereby obviated.

Referring now to Figs. l, 2, et, 5, and ll, the construction andarrangement of the platen and its supporting and controlling deviceswill be explained.

As already mentioned, the carriage X consists, essentially, of arectangular frame of metal, supported at the front by a roller orrollers Z and at the rear by lugs or arms m, respectively, travelingupon ways or guides 'u and w. Rising from each end of the frame ofcarriage X is apost or standard L',having a slot or opening c', of theform best illustrated in Figs. l, 4, and --that is to say, of increasingwidth toward the top-and having its rear wall curved (advisably, thoughnot necessarily) upon an arc of a circle of which the centeris the axisof a rock-shaft M', seated in suitable bearings or boxes at the rearside of the frame of the carriage X. The rear wall of the slot oropening c has at its upper end a seat or depression c2, above which isan overhanging arm or portion c3. The rockshaft M is formed or furnishedwith two forwardly extending arms CZ' and e', each of which passes closeto the outer face of one of the standards L and beyond or in front ofthe slot or opening therein, as shown in Fig. 2. One or both of thesearms is or may be extended somewhat in advance of the carriage X or toother convenient point, and there fashioned into a lift or thumb-piecef', by which to lift the same and cause the rockshaft to turn in itsbearings. Obviously, the two arms being rigidly connected to or madeintegral with the rock-shaft, they must rise and fallin unison.

N' indicates a rotatable platen, which is represented in the form of acylinder, but which may be polygonal in cross-section, if preferred.This platen or roll is advisably made in the form of a light woodenshell, covered on its outer surface with rubber, as usual, and it isfurnished at each end with a metallic bushing-ring g', which at one endof the roll is formed with teeth or cogs, as shown in Figs. l, 4, and 5.The rings g' rest and turn upon shouldered disks or heads O', (best seenin Fig. 11,) which disks are carried by a flat metallic bar P', the endsof which project beyond the disks and beyond the'ends of the roll orplaten and pass into and through the slots c' of the posts or standardsL', the ends resting upon the arms (Z' and e' of the rock-shaft M', asshown in Figs. l and 2. From this construction and arrangement of partsit follows that if the arm d or `latter is lifted.

e' be thrown up the bar P' will be caused to rise with them, and owingto the increasing inclination of said arms the bar will fall against andride upon the curved rear wall of the slot e' until the upper edge ofthe bar enters the seats c2 and is arrested in its risc. The furtherelevation of the arms d' e' will then cause the bar P' to turn upon itsupper edge as a`center, thus carrying it-s face from a vertical to ahorizontal plane, or, in other words, the elevation of the arms carriesthe bar P' from its normal position (indicated in Figs. l and 2) intothe position indicated in Fig.' 5.

Pivotally attached to one of the disks or heads O of the platen is a dogor pawl Q', the forward end of which is inclined both ways from itslowest point, said doubly-inclined end being arranged to overhang and toengage with the teeth of the toothed bushing or ring g', as shown inFigs. l, 2, and 4, being held in engagement therewith by a spring 7L'.The pawl or dog, while yielding and permitting the platen to be turnedforward or backward upon the application of slight force, holds itfirmly enough to cause it to maintain at all other times a fixedrelation to the heads or disks O', and inasmuch as the heads or disksare incapable of rotation upon bar P', it follows that the platen-rollturns through about one-quarter of a revolution with bar P' as the Theprinting-point is at the lower side of the platen when the latter is inits normal position. Hence upon the lifting and turning of bar P' itwill be brought up to the front of the roll as the latter stands in itselevated position.

To retain the parts in the elevated position for the purpose ofpermitting corrections to be made, &c., a rest or lug t", beveled on itslower side, is made to project from post or standard L' in such positionthat as the arm d' of rock-shaft M' rises, said arm, which is madesomewhat elastic, shall ride over the beveled face and rest upon the topface of the rest or lug i', the parts remaining in such position untilthe arm d' is sprung outward and allowed to descend again with theplaten.

To facilitate removal of the platen the opening or slot c' is left openat the top, or may be so left, though this is not essential.

R' indicates a pointer or index attached to the main frame of themachine and extending toward the platen, approaching close to the sameat a point midway between the sides or ends of the machine, or directlyin line with the printing-point, as shown in Figs. l and 2. This indexor pointer, which preferably rises from the guide-bar V, but which maybe elsewhere attached, is so curved or shaped that its upper end bearsupon or very nearly touches the platen or the paper thereon when theplaten is thrown up to the position shown in Fig. 5, and at the point towhich the printing-line is brought by such elevation of the platen. Itwill therefore be seen that if it be desired to maken correction it isonly IOO IIO

IZO

necessary to elevate the platen to bring the line to View, era-se themisused character, if there be one, move the carriage in one or theother direction until the pointer It' covers the point where a characteris to be printed, then drop the platen and strike the appropriate key.In this manner and without the use of any scale whatever,corrections-may be made with celerity and certainty. Itis of coursenecessary to provide a paper clamp or holder which shall permit theproper line spacing or feeding of the paper, and which shall preservethe paper in proper position under the different adjustments of theplaten. To this end the disks or heads O are both provided with arearwardly-projecting arm j', which arms are connected by a cross-rodK', so mounted as to prevent rotation. IIung or hinged upon this rod isa curved plate or shield S, which extends from the rear side of theplaten downward beneath the platen to a point somewhat in rear of theprintingline, carrying at its lower and forward edge a small roller T'of a length nearly equal to that of the guard or plate S. This roller isfree to turn in eyes formed upon the plate or guard S, and by bearingagainst the paper just in rear of the printing-line holds it closelyagainst the platen. Extending forward from the plate or guard S andupward in front of the platen are two curved arms U', which support andgive direction to the paper as it is advanced or fed forward, said armsserving to turn. the sheet back over the top of the platen.

A spring or springs V, coiled about the rod K', secured at one endthereto, and bearing at the other end against the rear face of plate orguard S', serves to press the guard toward the platen and to hold theroller T against the platen or against the platen between the roller andthe platen, as will be readily understood.

To turn the platen for line-spacing, Iprovide an arm or lever IV', whichis pivoted at one end to one of the disks O', and at its other endfashioned into a thumb-piece, as shown in Fig. 5. This lever carries adog or pawl z5', which engages with the teeth of bushing or ring g', andas the lever is thrown forward turns the platen a distance correspondingto the swing or throw of the lever.

The threw of the lever is determined by a turn-button or stop m, havingtwo stopfaces at different distances from the screw or pivot about whichit turns, the lever being normally drawn backward or outward by a springn, Fig. 5.

I do not broadly claim in this application the combinationofsupporting-bar, disks or heads carried by said bar, and a platen orroller mounted and arranged to rotate upon the heads or disks, as thatconstitutes the subject-matter of application, SerialV No. 0,922, ofeven date herewith, nor do I broadly claim in the present application apaper-clamp provided with arms extending upward from the clamp iu frontof the roll,

as that constitutes a feature of another application of even dateherewith, Serial No. 340,921.

It is particularly to be noted that under the construction herein setforth there is no necessity for moving the paper upon the platenrelatively to the pressure device or clamp by which the paper 'is heldagainst the platen in order to bring the printing-line to the properpoint or position for inspection. On the contrary the platen, paper, andclamp move as one in making this exposure of the work, and there isconsequently no liability of disarranging the paper or interfering withalinement, as is the case where it is attempted to attain the result byrotating the platen relatively to the paper-clamp iirst in one and thenin the other direction. It will also he observed that the fixed pointeror indicator is so located that it closelyv approximates theprinting-point of the printing-line, when ,without disturbance of theprinting relation of the platen, paper, and clamp, the printingpoint isexposed to view.

No claim is made herein to the mechanism herein shown and described forfeeding and shifting the hiking-ribbon, but said subjectmatter isdistinctly reserved for and is em.- bodied and claimed in application,Serial No. 444,925, lcd August 29, 1302, as a division of thisapplica-tion, for purposes of an interference contest.
